Square Appointments Custom Kiosk

Looking for a freelancer to create a Square Appointments Custom Kiosk that is specifically designed for payment processing. I have specific hardware requirements in mind and am looking for someone with experience in creating custom kiosks. The key feature I want to include is user authentication to ensure the security of the payment process. Custom branding is also important to me to ensure the kiosk fits with my brand. Additionally, real-time data sync is ideal to keep track of all transactions. Ideal skills for this project include experience in payment processing, kiosk design, and software development.
